Not true anymore. There's anything from the DIY kit with Youtube instructions to the full manufacturer service at a high premium. Personally: 2 visits to Calfee Designs in CA, I would trust them with any repair needed on my carbon frame.
Remember the aluminum frames that would get junked after getting a bad ding on the top tube ? Short of buying Ti, most metals have the same risks as carbon when it comes to damage and the effects on resale value, etc...
